Question

Define an acid and give two examples each of organic acid and inorganic acid
2. Differentiate between a strong acid and a weak acid. Give two examples of each.
3. (a) What is basicity of an acid? (b). Mention four physical properties of an acid.
4. Compare and contrast the electrical conductivity of HCl and CH3COOH

Answer 1

Answer:

Explanation:

1.

• Acids are substances that have free H₂ ions when dissolved in H₂O.

• Non-metallic oxides dissolve in H₂O to form acids.

E.g. Organic acids - Tannic acid , Citric acid

    Inorganic acids - HCl , H₂CO₃.

2.    Strong acid

• Strong acids are the strongest of all acids.

• They range from 0-1 in the pH scale.

E.g. H₃PO₄ , Lactic

NOTE:  All organic acids are weak acids

        Weak acid

• Weak acids are the weakest of all acids
• They range from 2-6 in the pH scale.

E.g. HCl , H₂CO₃

3. (a). The number of H₂ atoms in an acid is known as its basicity.  

   (b). ⇒Acids are sour in taste.

         ⇒ They are corrosive in nature.

         ⇒ They react with bases ( neutralization ) to form salts.

        ⇒ They turn litmus paper red.

4. Sorry ! I haven't learnt this yet so don't know the answer.

      Hope you are happy with the answer !
